This invention relates to typewriting-calculating machines with totaltaking mechanism, and to similar machines.

According to the invention, any or all oi the column totalizers in amachine of the class specified are combined with accumulators orsumming-up devices, and each accumulator is arranged to be selectivelycoupled with the corresponding column totalizer. The units comprising atotalizer and its accumulator, will be referred to as doubletotalizers."

By these means, values which have been introduced into the columntotalizers, are stored in the corresponding accumulator for later use,so that calculations involving accumulation of values, are easy andsimple.

In the accompanying drawings, an accounting machine to which theinvention has been adapted, is illustrated partly by way of example.

(1) General description The column totalizer I and the accumulator 2together constitute a double totalizer.

In the example illustrated, the accumulator 2 is superposed upon and ismounted to swing in a vertical plane at the top of the column totalizerI, to be coupled with and uncoupled from the column totalizer I. By aU-shaped manipulating lever 3 the accumulator 2 can be coupled with thecolumn totalizer I, and the species of the accumulator 2 can be setpreliminarily by manipulation of the same lever.

The cover 4 of the accumulator 2 is slotted at 5 to display numberwheels 6 forming part of the accumulator '2. The numbers "0 to "9 areplaced on the wheels in anti-clockwise sequence. The cover 1 and acontrolling plate 8 of the column totalizer I define a slot 9 displayingnumber wheels Ill forming part of the column totalizer I on which arealso placed the numbers 0 to 9 in anti-clockwise sequence.

The means for securing the column totalizer I to the totalizersuspension rail II of the paper carriage, not shown, of the accountingmachine on which it is suspended will be fully described in section IIThe suspension and securing means for the column totalizer and theaccumulator with reference to. Figs. 19, 20 and 21.

(2) The arrangement of the, mechanism in the column totalizer 5Referring now to Figs. 1 and 2, a bar 15 extends through the frame ofthe column totalizer I and is held against its side plates I2 and I4 byscrews I6. A locking lever I1 (Fig. 5) is mounted to swing on the bar I5for the hundredths denomination of the column totalizer I.

At its rear end, this locking lever I1 has a fork I8 and when thelocking lever of the hundredths denomination of the column totalizer Imoves into active position relatively to the master wheel I2, areleasing finger I9 whose upper end is shown in Fig. 2, engages in thefork for preparing the corresponding denomination for a calculatingoperation. A spring 2I whose upper end is attached to the locking leverl1 and whose lower end is anchored to a rod secured in the side platesI3 and I4 of the column totalizer I, tends to turn the locking lever I1clockwise about the bar I5. The normal position of the locking lever I1is defined by an abutment 22 on the locking lever I1 bearing against anadjustable screw 23 in a transverse bar 24 which is secured between thetwo side plates I3 and I4 of the vertical totalizer I.

In this normal position, a tooth 25 on the looking lever I1 engages inany tooth space between the teeth of a spur gear 26. The spur gear 26 ismounted to rotate on a shaft 32 which is secured to the side plates I3and I4 by screws 1 I. It is equipped with three tens-transfer teeth 21and a flange 30 which has a semi-cylindrical recess 29 opposite eachtens transfer tooth 21. The arrangement of the spur gear on the shaft 32is best seen in Fig. 7. The spur gear will be referred to as the "maindriving wheel 33."

The locking lever I1 is equipped with a tooth 54 positioned between thebar I5 and the abutment 22 for cooperation with a locking lever in theaccumulator 2, as will be described in section 6, The arrangement of themechanism in the totalizer. In the present instance, this is the lockinglever of the hundredths denomination in the accumulator 2.

An extension 35 of the locking lever I1 beyond the abutment 22 is forkedat 36 and has prongs 81 and 39 cooperating, respectively, with inclinesll and 40, Fig. 8, on the upper and lower edges, respectively, of thefree end of a coupling arm 4I Journaled on the projecting hub 49 of agear ill rotatable on a shaft 5|, as hereinafter explalned.

Mounted to rotate on a rivet 42 in the free end of the coupling arm 4|is a coupling gear 42. A shaft BI is secured in the end plates I3 and I4of the column totalizer I, and on it pairs of transmission gears 44, 45,Fig. '7, are mounted for free rotation. The width of each coupling gear43 is equal to the overall width of a pair of transmission gears 44 and45, so that the coupling gear engages and connects the two otherwisefreely rotatable transmission gears 44, 45 of a pair.

The left-hand side of the coupling arm H is recessed at 46 for thereception of another coupling gear which is similar to the gear 43, butis allotted to the next higher denomination of the column totalizer I.In the normal position of the coupling arm 4|, the coupling gear 42rests on a locking bar 48, Fig. 2, which is secured in the side platesI3 and I4 of the column totalizer I and, by engaging between adjacentteeth of the gear 43, holds the coupling arm 4I against swinginganti-clockwise about the shaft 6|, preventing unintentional rotation ofthe coupling gear 43 in its inactive position.

The coupling arm 4| is not mounted directly on the shaft 5I but isseated on the hub 49 a an intermediate gear 50, Fig. 8, which in turn ismounted to rotate on the shaft 5|. The hub or distance sleeve 49 bridgesthe distance to the next higher place, as shown in Fig. 7. It will beunderstood that in this manner the coupling arm 4| and the sleeve 49 canturn independently of each other.

The intermediate gear 50 meshes with a zero setting gear 52 which ismounted for free rotation on a shaft 54, secured to the side plate. I3and I4 by screws 53. The zero setting 52 is made integral with zerosetting disc 55 which has two zero setting teeth 56, for cooperationwith the usual zero stop 51, Fig. 5. The zero setting gear 52 alsomeshes with the teeth 26 of the main driving wheel 33.

The number wheel ID of the hundredths denomination is provided with azero setting gear 58, Fig. 5, meshing with the spur gear 52. The numberwheel I I), with its spur gear 58, is mounted to rotate freely on ashaft 60 which is secured in the side plates I3 and I4 of the columntotalizer I by screws 59.

The intermediate gear 50, meshes with the transmission gear 44 on theshaft 6|. The corresponding transmission gear 45 is mounted at the rightof the gear 44. If the gears 44 and 45 are not in active positionrelatively to the master wheel, the same are free to rotate quiteindependently of each other, so that any tens transfer in the column'totalizer I is performed independently of the accumulator 2, and viceversa. Transfer of values is only possible from the column totalizer Ito the accumulator 2 when the corresponding driving gear, say 26, isengaged with the master wheel I2, at which time only are thetransmission gears 44, 45 connected by the wide coupling spur gear 43 onthe arm U to rotate as a unit.

The transmission gears 44 and 45 are spaced apart by their bosses 62extending beyond the bodies of the gears, as shown in Fig. 9, and the-teeth of gears 44 are narrower than the thick ness of their bodies, sothat a free space 63 is formed at one side. The clearance made up by thebosses 62 and the set-back of the teeth at 63 is indicated by 64 in Fig.7 and is provided to afford clearance for the tens transfer teeth 65,Fig. 5, on the accumulator driving wheels 66 journaled on the shaft I15of the accumulator 2, as will be fully described in section (6) A flap61 (Fig. 5) extends transversely above all of the ten calculatingdenominational drive wheels 26, etc. in the column totalizer I and ismounted in the side plates I3 and I4 by trunnions 68 for cooperationwith the abutments 22, etc.

A shaft 10 is secured in the side plates l3 and I4 of the columntotalizer I by screws 69. On this shaft 10, a locking-wheel lever 1I,Fig. 5. somewhat similar to the locking lever I1, is arranged at thatdecimal place of the column totalizer I which is the next higher fromthe hundredths denomination, to swing about the shaft. A spring 12 whichis attached to the lockingwheel lever 1| at one end, and anchored to therod 20 at the other, tends to turn the lever 1I clockwise about theshaft 10, and its normal position is defined by an abutment 13 on thelever engaging an adjustable screw 14 in the transverse bar 24. Theabutment cooperates with the flap 61.

A fork 15 at the rear end of the locking-wheel lever H s arranged tocooperate with the releasing finger I 8, Fig. 2 when the decimal gear 84of the column totalizer I moves into engagement with the master wheelII. The finger I! releases the corresponding calculating gear train fora calculating operation.

A tooth I8 on the locking-wheel lever 'II which corresponds to the tooth84 of the locking lever I! at the hundredths denomination, is bentto theright for a distance equal to the space, between adjacent denominationalorders to cooperate with a locking lever 11 in the accumulator 2. aswill be described in section (6).

A transmitting pinion I8, Figs. 2 and 13, a Maltese gear 80 and areceiving pinion 8| are journaled to turn together on a stud I8projecting laterally from the locking wheel lever 'II. The parts I9, 80and 8| together constitute the usual locking andtens transfer wheel andthe unit will be referred to as the locking wheel 82. The transmittingpinion I8 of the locking wheel 82 of the tenths decimal place mesheswith the teeth 83 of the driving wheel 84 which is allotted to thetenths decimal place of the column totalizer I, said wheel 84corresponding to the main driving wheel 33 of the hundredths calculatingp ace.

The Maltese wheel portion 80 of this locking wheel 82 bears on theflange 80 of the main driving wheel 33 of the hundredths denomination;and the receiving pinion M of the locking wheel 82 is engageab'le by thetens-transfer teeth ii of the main driving wheel 33 of the hundredthsorder.

A stationary locking bar 85 (Fig. 2) extends through a slot 80 in thelocking-wheel lever II and is secured in the side walls i3 and I 4. Inthe normal inactive position of the totalizer, one of the tooth spacesbetween the teeth of the Maltese gear 89 or the locking wheel 82 of thetenths decimal place engages over the locking bar 85, as shown in Fig.2.

A forked member 81 (Fig. of the locking wheel lever "II engages the freeend 88 of a coupling arm 89, as best seen in Fig. 5. The coupling arm 89and the coupling gear 41 which is mounted to turn on it, correspond asto their arrangement, to the coupling arm 4i and its coupling gear 43for the hundredths denomination. As plainly shown in Fig. 5, the trainof gears allotted to the hundredths decimal place and comprising thegears 33, 52, 43, 50, 58, I0, 44 and 45 is similar to the gear train forthe tenths decimal calculating place and these parts of the tenthsdecimal place will not be detailed.

In the next higher, or comma, place of the column totalizer I, acalculating operation must not occur. To prevent a calculatingoperation. a forked comma locking member 90, Figs. 2 and 5, forked atthe lower end 82 is provided on the fulcrum shaft I5 of the columntotalizer I the forward prong 9| of which abuts against the rod 20. Whenthe comma space arrives at the printing point, the finger I9 engages inthis fork 82 and cannot rock in the direction of the arrow 93 in Fig. 2,since the prong 9| bears against the rod 20 and arrests the commalocking member, so that no calculating operation can b started in thecolumn totalizer.

It will be necessary to effect a tens transfer from the tenths decimalplace of the column totalizer I to the units of dollars denominationof-the column totalizer. For this purpose, the main driving wheel 84, asshown in Fig. '7, which is allotted to the comma place, is connected tothe main driving wheel 84 of the tenths decimal calculating place byrivets 84 so that the main driving wheels 84 and 84 act as a unit.

In the comma place, instead of the trains of gears allotted to allcalculating orders of the column totalizer I, spacers 88 and 88, Fig.'7, are inserted on the corresponding shafts BI and 84 of the totalizer,and a blank roller 81 is arranged on the shaft 80, Fig. 1, instead of anumber wheel I0.

The mechanisms described for the hundredths and tenths decimal places ofthe column totalizer I, as shown in Fig. 5, are also allottedalternately to the next higher calculating denominations that is, theunits, tens, hundreds, etc., decimal places. The arrangement of theseparts will therefore not be detailed. It should be noted, however, thatthe locking levers of the units calculating decimal places etc;, areequipped with a unit locking wheel as wheel 82 in the tenths decimalplace (Fig. 13).

At the left of the units of dollars calculating denomination, a lever88, as best seen in Figs. 2 and 5, is mounted to swing on the shaft I5.Its upper end 98 extends forwardly and into a, notch in the flap 8'! atI00. The rearwardly extending arm I02 of a holding member IOI attachedto the flap 61, projects below the end 89 of the lever 98. A spring I03which is attached to the lever 98 at one end, and anchored on the rod 20at the other, tends to turn the lever 98 clock wise about the shaft I0to cause the end 99 of the lever 98 to exert pressure on the arm I02 atthe rear end of the holding member IOI of the flap 61, to hold the flapyieldingly at its limit' of counterclockwise travel. in consequence, the

flap 6'! bears on the abutments 22 and 13 of the respective locking andlocking-wheel levers i7! and II allotted to the several calculatingorders of the column totalizer. This is the normal position of the flap6'! which, in turn, holds the lever 98 in its normal position wherein alocking tooth I04 on the lever 98 engages in that tooth space betweenthe teeth I05 of the main driving wheel I08 of the tens denominationwhich is presented to the locking tooth at the time. By these means, theslack of the main driving wheels 33, 84 etc. produced by theircooperation with the tens transfer and locking wheels 82, I01 and so on,and in the connected trains of gears at the individual denominations ofthe column totalizer .I, is taken up.

The arrangement of such a lever 88 and the parts co-operating therewithhas also been selected at the left of the eighth calculatingdenomination place or ten thousands order.

(3) The operation of the column totalizer when a value is introduced Theoperations which are performed when a value is introduced into thecolumn totalizer I, are substantially similar in the individualcalculating orders, and therefore only the introduction of a value intothe units of dollars calculating order of the column totalizer I will bedescribed by way of example.

When the transmitting pinions I8, I08, etc., of the locking wheels 82,I" etc., of the individual calculating denominations engage in the teethof the main driving wheels 84, III etc. of next.

higher order, (Fig. 2), the main driving whcels 84, III cannot berotated. Unintentional rotation of each individual main driving wheel88, 84, III etc., is prevented by the teeth of the Maltese wheel 30, II2 of the locking wheels 02, I01 etc., which bear on the flange 30, H ofthe main driving wheel 33, 04, III etc. of the next lower calculatingdenomination.

After the units of dollars denomination of the column totalizer I hasmoved into active position with relation to the master wheel I2, and thewell known calculating key-not shown-for the value to be introduced hasbeen depressed. the releasing finger I0 is turned in the direction ofthe arrow 93, and, since it projects into the fork N3 of the lockinglever II4 allotted to the units of dollars denomination, it swings thelooking lever anti-clockwise about the bar I5, Fig. 3, against itsspring II5. At the same time, the abutment IIG of the locking lever H4is lifted clear of the screw 1 in the stationary bar 24 to rock the flap01 clockwise about its trunnions 59. The arms I02 of the holding membersIOI secured to the flap 51 act on the arms 99 of the two levers 98 Figs.3 and 5, only one lever 99 being illustrated, and swing the levers 90anticlockwise about the bar I against their springs I03 to disengage thelocking teeth I04 of the levers 90 from the teeth I05 of the maindriving wheels I05 and II9 (Fig. 7) so that these are free to turn. Alsothe locking wheel I01, Fig. 13, of the locking lever II4 partakes in itsanti-clockwise movement, and the transmitting pinnion I03 of thislocking wheel I0 clears the teeth IIO of the units of dollars maindriving wheel III. At the same time, the Maltese wheel H2 is with drawnfrom the flange H9 or the. main driving wheel 9| of the comma place,and, since the flange I2I (Fig. 7) of the main driving wheel III of theunits of dollars denomination can rotate freely past the teeth of theMaltese wheel I22 of the locking wheel I23 0! the next higherdenomination, that is, the tens of dollars denomination, the maindriving wheel III of the units of dollars denomination can be turned bythe master wheel I 2.

When the locking lever I I4 of the units of dollars order has been swunganti-clockwise by the release finger l9, one of the tooth spaces of theMaltese wheel II2 of the locking wheel unit I01 engages the stationarybar I24 and thus prevents rotation of the locking wheel I01 on the saidlocking lever I I4.

When the locking lever I I4 of the units of dollars order is swunganti-clockwise, the prong I25 (Figs. 2-5) of the fork I26 at the end ofthe arm I21 of the locking lever lI4 engages the edge I23 of thecoupling arm I29 at the units of dollars order a short time after thelocking lever has started and swings the coupling arm I29 clockwiseabout the hub I30 of the corresponding spur gear I30 to disengage thecoupling gear III on the arm I29 from the locking bar 43. When thecoupling arm I29 has completed its clockwise movement the coupling gearI3I, as shown in Fig. ll meshes with the pair of transmission wheelsI32, I33 at the units order.

The value is now introduced into the column totalizer I, and the masterwheel I2 is rotated in the direction of the arrow I34 (Fig. 1) throughan angle correspondin to the value introduced. Since the master wheel I2meshes with the teeth IIO of the main driving wheel III of the units ofdollars order, this wheel is rotated in the direction of the arrow I35in Fig. 3, and transfers the value to the wheels I30, I30 and I31 whichrotate in the directions of the arrows I35 in Fig. 3. The number wheelI0 of the units of dollars order par-takes in the rotation oi its gearI31 in the of the comma place direction of the arrow .iland displays thevalue at the inspection opening 9 in the cover plate 8 of the columntotalizer I. The transmission oi the rotation of the intermediate gearI30 to the corresponding transmission gear I32 and to the accumulator 2through the twin gears III and I33 will be described in section (6).

When the value has been introduced, the releasing flnger I9, returnsinto its initial position, as shown in Fig. 2, and releases the lockinglever II4 whose abutment IIO now is returned against the screw H1 in thebar 24 by its spring I I5. At the same time, the abutment IIB releasesthe flap 51 and, through parts 99, IOI and I02, the levers 33 returninto their initial positions, Fig. 2, under the pull of their springsI03. Their teeth I04 now re-engage between the teeth I05 of the allottedmain driving wheels I 06 and III.

The locking wheel I01 of the locking lever I I4 at the units of dollarsorder partakes in the return of this lever into its normal position andthe transmitting gear portion I00 engages in the teeth i I0 of the maindriving wheel III of the units dollars order. The Maltese portion II! ofthis locking wheel I01 re-engages the flange H9 of the main drivingwheel 94 at the comma place, and locks the main driving wheel I I Iagainst rotation.

When the locking lever II4 returns, the prong I25 of its fork I23releases the edge I29 of the coupling arm I29 of the units dollarsorders which now swings about the hub I38 of the intermediate gear I30by gravity. When the locking lever II4 has about completed its return,the prong I39 of the fork I26 re-engages the edge I40 of the couplingarm I29, to insure the engagement of the coupling gear I3I with thestationary locking bar 49.

The operations performed in the units dollars orders are now completed,the value is typed on the paper supported by the paper carriage, and thecarriage is advanced another step in letter spacing direction to engagethe driving wheel 94 with the master wheel I2.

(4) The tens trans jar in the column totalizer If, owing to theintroduction of a value, in the units dollars orders of the columntotalizer I, a tens transfer to the tens dollars orders becomesnecessary, this is performed as follows while the value is beingintroduced:

It is known that the number wheels III rotate clockwise in addingoperations. When the number wheel I0 of the units of dollars order turnsfrom 9 to 0," one of the tens transfer teeth I40 of the main drivingwheel i I I of the units of dollars order, which rotates anti-clockwisestrikes a tooth I42 of the receiving pinion 3i of the locking wheel I23,Fig. 13, on the locking wheel lever of the tens place turning thelocking wheel I23 one step clockwise. This turning is not interferedwith by the Maltese wheel I22 since when the lockin wheel I 23 isturned, one of the recesses I43 in the flange I2I of the main drivingwheel II I of the units of dollars order is presented to thecorresponding tooth I40 of the Maltese wheel.

When the locking wheel I23 of the tens of dollars order is turnedthrough one stop, the main driving wheel I05 of the tens of dollarsorder is rotated anti-clockwise about the bar 32 since the transmittinggear portion of the locking wheel I23 meshes with the teeth I05 of suchmain driving wheel. Through the train of gears I 45.

I46, Fig. 7, which corresponds to the gears I86, I36 9. unit istransferred to the number wheel I of the tens of dollars order inadditive direction. The train gear I41, Fig. 11, of the tens of dollarsorder is also turned one unit but does not exert any action. To preventrotation of the twin gear I48 during this idle movement of twin gearI41, due to frictional engagement, means such as a blade spring I49.Fig. 2, in the shape of a comb may be provided, with tongues I50pressing againsteach of the twingears I48,- I33, etc., engaged with theaccumulator drive gears 262, 244, etc., of the individual orders. Afterthe locking wheel I23 of the tens of dollars order has been movedthrough one unit, the main driving wheel III of the units of dollarsorder has turned so far thatthe solid portion of the flange I2I on themain driving wheel III is again presented to the Maltese wheel I22 ofthe locking wheel I23 to provide an interlock.

() The operation of the column totalizer when total taking v When it isdesired to eliminate the value which has been introduced, by totaltaking, the following operations occur in the individual orders of thecolumn totalizer, as will now be described for the units place.

When the units of dollars order of the-column totalizer has moved intocalculating position, the well known total taking key, not shown, isdepressed and the releasing finger I9 is turned in the direction of thearrow 93, (Figs.'2-4) turning the locking lever I I4 anti-clockwiseabout the bar I5. This swinging movement of the lever II4 causes theunlocking of the train of gears 'I I I, I36, I5l, I30, I31 as describedin section (3).

Furthermore the zero stop 51 is'shifted in the direction of the arrow.I53 in Fig. 5, and moved into the path of the two zero setting teeth I54on the disk I5I of the zero setting gear I36, Fig. 5.

Now, the master wheel I2 is rotated against the arrow I34 in Fig 1, andthe main driving wheel III of the units of dollars order and the trainof gears I36, I5I, I and I31 allotted to the units of dollars order aredriven in the direction of the arrows I55 in Fig. 3 to reversely turnthe numeral wheel I0. At the moment the number wheels I0 of the units ofdollars order is turned from 1 to 0, one of the zero setting teeth I54on the disk I5I of the zero setting gear, I36 engages the zero settingstop 51, Fig. 5, and limits themtation of the said train which nowoccupies its zero position, as shown in Fig. 2. At this moment, thereleasing finger I8 releases the locking lever II4 of the units ofdollars order and the parts connected to it, for return into theirinitial positions, as also described in section (3), and shown in Fig.2. The zero setting stop 51 is returned into its normal position againstthe arrow I53 in Fig. 5.

THE ACCUMULATOR (6) The arrangement of the mechanism in the accumulatorThe accumulator 2 is pivoted to rock bodily on the shaft I58 which issecured in an eye I56 of cumulator 2 are placed on the shaft I58 betweenthe eyes I56 and I51.

The side walls I59 and I60 of the accumulator 2 are connected bytransverse bracing members I6I, I62 and I63, Figs. 2, 3 and 4, to whichthe cover plate 4 is secured by screws I64, Fig. 1.

At the front side of the double totalizer, lugs I61 and I65 on the sideplates I59 and I60, respectively, of the accumulator, are arranged forcooperation with abutments I68 and I66 on the respective side plates I3and I4 of the column totalizer I, as best seen in Fig. 19. An offsetguiding lip I10 projects upwardly from the side plate I3 of the columntotalizer I, and a similar pilot lip I69 is-provided on the other sideplate I4 as best shown inFigs. 14 to 17 to guide the superposedaccumulating section to its seating position on the column totalizer.

In the lowest calculating order, that is, in the hundredths place of theaccumulator 2, the following parts are arranged.

The transmission gear (Figs. 5 and 11) of the hundredths order of thecolumn totalizer is arranged for cooperation with the teeth I4I of thehundreds order driving wheel 66 on the shaft I15 of the accumulator. Thedriving wheel 66 as shown in Fig. 5, is similar to the driving wheel 33in the column totalizer I, having three tens transfer teeth 65 and aflange I14 with depressions I13. A reversing pinion I16 Journaled on ashaft I11 meshes with the teeth "I of the accumulator driving wheel 66.The ends I18 and I19 of the shaft I11 are guided in slots I80 and I 8I(Figs. 1, 5, and 1'1) in the side plates I59 and I60, respectively.There are as many reversing pinions on shaft I11 as there are drivingwheels, each pinion being constantly in mesh with its respective drivingwheel.

Arranged above the shaft I11 is another shaft I 83' which is secured inthe side plates I59, I of the accumulator 2 by screws I82, Fig. 1, onwhich shaft is journaled an idler gear I84 meshing with the teeth I" ofthe accumulator driving wheel 66. This idler gear, through a gear I85,operates the number wheel 6 of the hundredths order of the accumulator 2shown in Fig. 1. All the number wheels 6 of the accumulator are mountedto rotate about a shaft I81 which is held by screws I86. The arrangementof the numbers on the wheel 6 is shown in Fig. 3, and is similar to thatof the numbers on the column totalizer wheels I0.

In the hundredths order of the accumulator 2, a locking tooth I88, Fig5, on a locking lever I89 engages between the teeth "I of the drivingwheel 66, normally holding the wheel 66 against rotation. The lockinglever I89 is mounted to swing about a shaft I 9I which is secured byscrews I90, Fig 1. A spring I92 which is attached to the upper end ofthe lever I89 and anchored on a rod I94, pulls the lever against a screwI91 which is adjustable in a fixed cross bar I96, this being the normalposition of the locking lever I89. The ends I98 of the bar I96 areinserted in holes I99 of the side plates I59 and I60, and held againstturning. Only the hole I99 in the side plate I59 is shown in Fig. 5.

The lower end of the locking lever I89 is provided with a horn 200, theconvex face 20I of which is engaged by the tooth 34 of the locking leverI1 already described in section (2).

An incline 202 provided on the back of the locking lever I89 contacts alocking flap 203 extending across the accumulator frame. The flap 208has a pair of headed trunnions 204, one of which is shown at the rightinFig. 19, mounted to rotate in the side plates I58 and I50. The loweredge of the locking flap 203 is forwardly bent and terminates in acurved face 205 to co-act with a node 208 on the rear edge of thelocking lever I89, the curved edge 205 also being capable of entering arecess in the rear edge of rod 2 holds an abutment 2" of the lockingwheel lever 11 against a screw 2H in the statlonary bar I. A horn 2|! atthe lower end of the locking wheel lever 11 has a curved front edge 2|!for cooperation with a offset lug 18 on the locking wheel lever II atthe tenths calculating order of the column totalizer, as shown in Fig.5.

An incline 220 on the back of the locking wheel lever is arranged forcooperation with the looking flap 202, whose curved face 205 canc00perate with the edge 22I of a node 222 on the locking wheel lever'I'|, or project into a recess 222 in the lever 11.

A locking bar 225, Fig. 2, secured in the side plates I59 and I andsimilar to the transfer unit locking bar 2, extends, with a clearance,through a slot 222 in the lever 11.

A headed rivet 225 is inserted in the lever 11 and supports a tenstransfer and locking wheel 22! which will be briefly referred to as thelocking wheel and is similar to the locking wheel 22 at the tenths orderin the column totalizer I. The locking wheel 221 comprising atransmitting gear 228, a Maltese wheel 22!, and a receiving gear 220,Fig. 11. The teeth 228 of the locking wheel 22'! mesh, in the normalposition of the lever 11, as shown in Fig. 2, with the teeth 23I of thedriving wheel 222 which is allotted to the tenths order and correspondsto the driving wheel of the hundredths place. 225 of the Wheel 22! reston the flange I'll, Fig. 11. of the driving wheel 55 in the hundredthsorder, and the other set of teeth 2" can cooperate with the tenstransfer teeth 55 of the flange I12 of the wheel 55.

As appears from Fig. 5, a train of gears 222, 2, 225 and I is allottedto the tenths calculating order which corresponds to the train of gearsof the hundredths calculating order, and so need not be described.

The next higher place is the comma place where no values must betransferred to or from the column totalizer I. This place isconsequently without the train of gears and locking levers of the otherorders. The driving wheel 232 of the tenths calculating order, Fig. 11,is connected to the driving wheel 258 at the comma place by rivets 231for the purpose of any tens transfer which may be required from thetenths order to the units of dollars order. Instead of a number wheel 5,a blank roller 28!, Fig. 7, is allotted to the comma place, while aspacer 239, Fig. 5, is arranged on the shafts, I82 and lil.

The parts allotted to the next higher, that is,

The Maltese teeth Ill) . the units of dollars order, in the accumulator,

correspond substantially to those of the hundredths order, but thelocking lever 240 of the units order is equipped with a locking wheel 2,like that allotted to the tenths order. The transmitting teeth 242 (Fig.2) of this locking wheel 2 mesh with the teeth 243 of the driving wheel2 of the same order, its Maltest wheel 245 is arranged to cooperate withthe flange 2" of the driving wheel 235 of the comma place, and itsreceiving teeth 2" cooperate with the tens-transfer teeth 24! of theflange 2" on the comma place driving wheel 23!.

The parts which have been described with refence to the hundredths andtenths calculating orders of the accumulator 2, are also allotted,alternately units of dollars to the tens, hundreds etc. calculatingorders in the accumulator, and will not be detailed.

Mounted to swing on the shaft I at the lefthand side of the lockingwheel lever 240 at the units of dollars order of the accumulator 2 is athree-armed lever 250. A tooth "I at the rearwardly extending end of thearm 252 of this lever engages in a notch 253 in the flap 202 and isarranged to cooperate with an arm 2" of a member 255 which is fixed tothe flap 202 behind the notch 253. A spring 251 connected to another arm255 of the lever 250 and anchored on the rod I94 turns the leveranti-clockwise and causes its tooth 25I to swing the flap 203 clockwisethrough the arm 254 of the member 255 until the flap bears on theinclines 258, 220 of the respective locking and locking wheel levers Illand 11, and this defines the normal positions of the flap 203 and of thethree-armed lever 250;

In this normal position, a tooth 250 at the free end of the dependingthird arm 259 of the lever engages between the teeth 2" of the drivingwheel 252 at the tens order to take up or compensate for the slackresulting from the cooperation of the driving wheels 55, 222 etc., andthe locking and tens transfer wheels 221, 2 etc. which increases fromorder to order.

A tooth 252 projects from the rear edge of the arm 252 of thethree-armed lever 250 for co operation with a cross rod or stay 2 in arockable locking frame 255 (Fig. 2). This bail, as best seen in Fig. 17,comprises a pair of arms 2" and 251, the rear ends of which are mountedto swing about a shaft 215 secured to the side plates I59 and IE0 of theaccumulator 2. The front ends of the bail arms support a detent rod 258which has the profile of a tooth and extends over the accumulatordriving wheels 65, 232 etc., of all denominations in the accumulator,for preventing unintentional rotation of the driving wheels. Each arm ofthe bail 255 is equipped with a spring 2', as shown for the arm 255 inFigs. 3, 4 and 17 which is secured to the adjacent side plate I59 or I62by a pin 212. The springs turn the bail 255 clockwise and hold theprofiled rod 259 between the teeth I'll.

The three-armed lever 250 and the parts 252 and 255 which arecooperating with it, are also arranged at the left-hand side of thethousands denomination in the accumulator 2.

(7) The operation of the mechanism when total taking in the columntotalizer and transferring the value to the accumulator additivelz/ Theoperation of the parts allotted to the individual calculating orders ofthe accumulator 2 is the same in each order, and so only the operationat the units of dollars order of the accumulator 2 will be described indetail.

In their initial positions, the locking levers24l" and the locking wheellevers 11, throush their locking wheels 221, 24! etc. (Fig. 11), preventrotation of the corresponding accumulator driving wheels 232, 244 etc.,in the same manner as described for the locking of the wheels 82, I01

etc. of the column totalizer I in section (3).

' and 14-1'1)--whose arrangement and operation will be described insection (14)--is thrown over from the uncoupling position in Figs. 2 and14 into the coupling position in Figs. 3 and 15. The accumulator 2 isswung bodily clockwise about the shaft I58 until the lugs I61 and I85 onthe side plates I" and I80 of the accumulator 2 bear on the abutmentsI88 and I68 on the side plates I3 and I4 of the column totalizer I. Thedrive ing wheels-88, 232 etc. of the calculating orders in theaccumulator 2 now mesh with the corre=- sponding transmission wheels 45,213 at the cor-' responding calculating orders in the columntotalizer I.

' When the column totalizer I shifts axially with the supporting bar IIof the paper carriage to engage its units of dollars driving gear III(Fig. 5) with the master wheel I2, the locking lever II4, as describedin section (3), is turned anti-clockwise by the releasing finger I8about the bar I5, as shown in Fig. 3, and its nose 214 acts on the nose215 at the lower end of the locking wheel lever 240 at the units ofdollars order of the. accumulator 2, swinging the lever 240 clockwiseabout the shaft I8I against its spring 216. The incline 258 on the rearedge of the locking lever turns the flap 203 anti-clockwise and thefront lower edge 205 of the flap 203 engages in the recess 211 in thelocking lever 240 while at the same time it engages the nodes 201- g or22I of the other locking levers I88 and locking wheel levers 11 whichare in their normal positions, and blocks them against unintentionalturning. At the same time, through the noses 200 and 34 and 2I8 and 18,the locking and locking wheel levers I1, H in the column totalizer I areheld against unintentional movement, that is, while an operation isperformed in the units of dollars order of the column totalizer and theaccumulator, all other denominational locking devices are locked againstoperation.

When the flap 203 (Fig. 5) is turned, the arms 254 of its members 255act on the ends 25I of the three-armed levers 250 which, as viewed fromthe left and the front of the column totalizer I (Fig. 5) are arrangedat the left of the fourth and eighth orders of the accumulator 2, andturn such levers clockwise about the shaft I8I against their springs 251to disengage the teeth 283 of the three-armed levers from the teeth ofthe driving wheels 282 and 218 at the fifth and ninth orders. In Fig. 5only one of said levers 250 is illustrated.

A short time before the three-armed levers 250 have completed theirdisengaging movement, their'teeth 283 collide with the cross bar on stay284, to turn the detent bail 285 anti-clockwise about the shaft 210against its springs 2H and return the profiled detent rod 288 from theteeth I1I, 23I etc. of the driving wheels 66, 232 etc. of theaccumulator 2 with its rib 288, to release said gears.

As the locking wheel lever of the units of dollars order in theaccumulator 2 moves clockwise about the shaft "I, the Maltese wheelportion 245 of its locking and tens transfer wheel 2 clears the flange248 of the driving wheel 238 of the comma place, and its teeth 242 clearthe teeth 243 of the driving gear 244 in the units of dollars order. Thedriving gear 244 and its train 218, 280 and units of dollars numeralwheel 8 are now ready for the reception of a value.

When the locking wheel lever II4 of the units of dollars order in thecolumn totalizer I turns anti-clockwise, its fork I28 turns the allottedcoupling arm I28 clockwise about the hub I30 of the intermediate gearI30. and the wide coupling gear I3I, as described in section (3),connects the pair of transmission gears I32 and I33 allotted to theunits of dollars order.

The value which has been introduced in the units of dollars order of thecolumn totalizer I is now withdrawn by total taking, as described insection (5) and, as the master wheel I2 is rotated in the direction ofthe arrow 28I (Fig. D, the train of gears III, I38, I30, I31, and thetotalizer number wheel III of the units of dollars order rotate indirections I indicated in Fig. 3 until one of the zero setting teeth I54of the flange I 5| engages the zero stop 51. In this position the numberwheel I0 of the units of dollars order displays "0".

When the intermediate gear I30 of the units of dollars order is turnedbackwards in the direction of the arrow I55 in Fig. 3, the transmissiongear I32 is also turned anti-clockwise, and the coupling wheel "I whichmeshes with it is turned clockwise and turns the other transmission gearI 33 anti-clockwise. The transmission gear I33, through its teeth turnsthe driving wheel 244 of the accumulator in the direction of the arrow282. The driving wheel 244 now transfers the total value to thecorresponding number wheel 8 of the accumulator through pinions 213 and280 which numberwheel turns in additive or clockwise direction andindicates the total withdrawn from the numeral wheel of correspondingorder of the column totalizer I.

The releasing finger I8 now releases the locking lever II4 on the unitsof dollars order in the column totalizer I and the lever returns intoits initial position, as shown in Fig. 2. At the same time, the nose 214of the locking lever II4 releases the nose 215 at the lower end of thelock-' ing wheel lever 240 at the units of dollars order in theaccumulator 2 whose spring 216 returns it into its normal position, Fig.2, with its abutment bearing against the screw 284 in the stationary barI88. The incline 258 of the returning locking wheel lever 240 releasesthe flap 203, and by the cooperation of the arms 254 of the members 255on the flap 203, with the teeth 25I of the three-armed levers 250, thelatter become free to return into their normal positions, Fig. 2 andtheir teeth 263 clear the cross stay 264 of the detent bail 265 which isnow returned into its normal position by the springs 21I turning itclockwise about its shaft 210, and the rib 268 oi the detent rod 269engages between the teeth of the driving wheels 66, 232 etc. and locksthem, as shown in Fig. 2.

The teeth 283 of the three-armed levers 250 are so positioned withrespect to the cross stay 264 that the rib 268 of the detent rod 268 isalready between the teeth of the accumulator driving wheels I1I, 23Ietc. before the coupling gear I" is moved clear of the transmissiongears I32, I33 owing to the return of the locking lever H4 in the unitsoi dollars order 01 the column totalizer I. This prevents overthrowingot the train 244, 235, 213, 233 after the throwing out or disengagement;of the coupling wheel 23I from its twin transmission gears.

In the locking position of the detent bail 265, Fig. 2, the rib 263 ofits detent rod 263 exactly aligns the number wheels 6 displayed throughthe slot '6 in Fig. 1.

When the flap 203 has returned into its initial position its inner sideagain engages the inclines 253, 232 and 223 of the locking levers I89,240 and 11 in'the several orders of the accumulator, and its front edge205 leaves the recess 211 in the locking wheel lever 240 at the units ofdollars order and recedes from the edges 201 and HI the nodes 206 and222 of the locking and locking wheel levers I63 and 11 at the othercalculating places, releasing the said levers, as shown in Fig. 2.

When the three-armed levers 250 have returned into their normalpositions as shown in Fig. 2, their teeth 260 again engage between theteeth of the accumulator driving wheels 262, etc.

When the locking wheel lever 240 at the units of dollars order of theaccumulator 2 has returned into its initial position Fig. 2, the teeth242 oi. its locking wheel I again come into mesh with the teeth 243 ofthe driving wheel 244 of the units of dollars order and its Maltesewheel 245 again engages the flange 246 of the driving wheel 236 in thecomma place, and now all parts of the units of dollars order in theaccumulator 2 have returned into the initial positions, shown in Figs. 2and 5.

When it is desired that when total taking from the column totalizer Ithe value should be transferred to the accumulator 2 subtractively, thehandle 3 (Figs. 1-4 and 14-17) is thrown into the P0sition illustratedin Fig. 4 to engage the reversing pinions 205 in the accumulator 2 withthe transmission gears I33 of the column totalizer I. In this case, thetrain 244, 213 and 280 of the units of dollars order is rotated againstthe arrows 282 in Fig. 3. The operation need not be described.

(8) The tens transfer in the accumulator The operations which areperformed during a tens transfer in the accumulator 2, are substantiallysimilar to the operations described with respect to the column totalizerI in section (4), and will therefore not be described.

It should be noted, however, that a rotation of the driving wheel 262 inthe tens of dollars order of the accumulator 2 in combination, forinstance, with a tens transfer from the units of dollars order to thetens of dollars order in the accumulator 2, and the correspondingrotation of the mating transmission wheel 236 (Fig. 7) at the tens ofdollars order of th column totalizer I does not influence the tens ofdollars calculating order in the column totalizer since the notillustrated locking wheel lever o'f the tens of dollars order whichcorresponds with the lever II i not swung by the releasing finger I9,and the coupling gear of the tens of dollars order is not coupled withthe twin transmission wheels 261, 236 of the tens of dollars order.Hence the transmission gear 231 turns idly with respect to transmissiongear 206. In order to'obtain an effective tens transfer in theaccumulator 2, it was necessary to provide a pair of transmission wheels44, 45 and 213, 236 etc. for each driving wheel 66, 232 etc.

When an accounting problem requires the additive introduction oil avalue into the column totalizer I and an additive transfer of this valueinto the accumulator 2, the manipulating lever 3 is moved clockwise fromits Fig. 14 position into the position illustrated in Fig. 16. Thereversing pinions I16, 233, 285 etc. in the accumulator 2 engage withthe transmission gears 45, 213 etc. in the column totalizer I in amanner which will be described in section I2. Since the operations inthe column totalizer I have already been described in section 3, thiswill not be repeated here.

When the locking lever I I4 of the units of dollars order in the columntotalizer I is swung counterclockwise, the parts I01, I23, I3I, 61, IOIand 30 operated by it are moved into the positions shown in Fig. 4. Atthe same time, the nose 214 of the lever II4 acts on the nose 215 of thelocking wheel lever 240 allotted to the units of dollars order of theaccumulator 2, so that the lever 240 together with the cooperating parts203, 255, 250, detent fail 265, and locking wheel I are moved into thepositions shown in Fig. 4.

When the main driving wheel III of the units of dollars order in thecolumn totalizer I is rotated in the direction of the arrow I35 in Fig.4, in conformity with the value to be introduced the wheel transfers thevalue to the corresponding number wheel I0 through gears I36, I30 andI31 which is rotated in the direction of the arrow I35 and indicates thevalue. When the intermediate gear I30 at the units of dollars orderrotates in the direction of the arrow I35, the transmission gear I32,and through the coupling gear I3I, the transmission gear I33, ar rotatedclockwise. The rotation of the transmission gear I33 is transmitted tothe reversing pinion 265 of the units of dollars order in theaccumulator 2 which turns in the direction of the arrow 289 and rotatesthe accumulator driving Wheel 24 4 and the train 219, 280 and 6 in thedirection of the ar rows 282 in conformity with the value to beintroduced, whereby this value is transmitted positively to thecorresponding number wheel 6 at the units of dollars order in theaccumulator 2,

(10) The introduction of a value into the column totalizer additivetyand the subtractive transfer to the accumulator If the accountingproblem requires the additivc introduction of a value into the columntotalizer I and a subtractive transfer thereof to the accumulator 2, themanipulating lever 3 is moved counterclockwise into the position shownin Fig. 15 for connecting the driving wheels 66, 232, 244, etc. in theaccumulator 2 to the transmission gear 45, 213 etc. of the columntotalizer I, Figs. 3 and 7. When now the train III, I36, I30, I3I, I31,II] for example of the column totalizer I is rotated in conformity withthe value to be introduced, in the direction of the arrow I35 in Fig. 3,the transmission gear I33 is rotated anti-clockwise by the gears I32 andI3I. The transmission gear I33 turns the driving wheel 244 which, inturn drives the train 213. 230 and 6 of the accumulator 2 against thearrows 282 to subtractively transfer the value onto the number wheel 6.

(11) The cancellation of the accumulator The cancellation of a valuewhich has been indicated by the number wheel 6 of the accumulator 2,requires backward transmission of this value into the column totalizer Iafter this has been set to zero by total taking.

The manipulation or state control lever 3 is moved counterclockwise intothe position in F18. 15, whereby the driving wheels 66, 232, 2 etc. ofthe accumulator 2 are directly connected to the transmission gears 45,213 etc. of the column totalizer I.

For instance, if the number wheel 6 of the units of dollars orderindicates the value 3 in the accumulator 2, this value 3 is cancelled asfollows:

When the units of dollars order of the column totalizer I has moved intoactive position with relation to the master wheel I2, the calculatingkey for the value not shown--is depressed for introducing the value 3,the units of dollars order of the column totalizer I and of theaccumulator 2 are unlocked by the levers I I4 and 240, and the train ofgears III, I36, I5I, I30, I31 and I0 of the units order in the columntotalizer I is rotated three steps in additive direction, as shown bythe arrows I35 in Fig. 3, the intermediate gear I30 transmitting thevalue 3 to the twin gear I33 through transmission gear I32 and couplinggear I3I. The transmission gear I33 rotates clockwise to drive the train2, 219, 280 and 6 of the units of dollars order in the accumulator 2three steps in a direction against the arrows 282. When this rotationhas been completed, the number wheel 6 of the units of dollars order inthe accumulator 2 again displays a 0, while the number wheel I0 of theunits of dollars order in the column totalizer I displays "3." Thisvalue 3" in the column totalizer I is cancelled by total taking in thecolumn totalizer I, after the manipulating state control lever 3 hasreturned the accumulator 2 into its initial position, as shown in Figs.2 and 14.

(12.) The arrangement of the coupling and locking means for theaccumulator A headed screw 290, Figs. 14 to 17, is inserted in theleft-hand side plate I4 of the column totalizer I as the pivot for theleft-hand arm 293 of the manipulating lever 3, a bearing 292 in the armbeing seated on the shank 29I of the headed screw 290, as shown in Fig.17. A blade spring 295 is riveted to the arm 293 at 293 and its free endsupports a pin 296 sliding in a hole 291 in the arm 293. The inner endof the pin 296 which projects from the hole 291 in the arm 293 ishemispherical for cooperation with three hemispherical depressions 298,299, and 300 in the left-hand side plate I60 of the accumulator 2,holding the manipulating arm in any oneof the three positions.

The lower end of the arm 293 is made with a cam plate 30I whose frontedge 302 is curved in ogee form. In the normal position of themanipulating lever 3, Figs. 2 and 14, the high point of the curved frontedge 302 engages beneath the end I19 of the reversing pinion shaft I11which it will be remembered, is mounted to slide in the arcuate slotsI80 and I8I in the side plates of the accumulator 2 to hold the pinionshaft I11 against downward movement. At the lower end of the front edge302, a semicircular seat 304 is formed by the upper edge of a hook 303shaft I11 when the manipulating lever 3 is in the position shown in Fig.15. A slot 305 is formed at the upper end of the front edge 302 alongwhich the end I19 of the reversing pinion shaft is free to slide whenthe manipulating lever 3 is in the position shown in Fig. 16.

An angular cam slot 301 i formed in the rear portion 306 of the camplate 30I, and into this projects a guide pin 308 secured in theleft-hand side plate I60 of the accumulator 2. In the position accordingto Fig. 15, this pin is in the straight part 3I0 of the cam slot, and inthe position illustrated in Fig. 16 it is in the curved part 309. By thecooperation of the pin 308 and the cam slot 301, a definite position isgiven to the accumulator 2 which swings about the shaft I58 on thecolumn totalizer I, for all positions of the manipulating lever 3. Arecess 3| I is made in the lower edge of the angular slot 301 in itscurved portion 309. In the initial position of the manipulating lever 3,as shown in Figs. 1, 14, and 17, an abutment 3I2, projecting from thelefthand side plate I60 of the accumulator 2 engages in the recess 3".The abutment 3I2 is the left-hand end of a locking rack 3I3, a best seenin Fig. 18. The edge 3 of the abutment is curved and, depending upon thedirection of -movement of the manipulating lever 3 is acted upon by thelower edge 3I5 of the curved part of the angular slot 301, or with a.hook 3I6 at the upper side of the recess 3| I.

The locking rack 3I3 (Fig. 18) is guided in a slot in the left-hand sideplate I50 by its abutment 3I2, and in a similar slot in the right handside plate I59 by an extension 3I1. A spring 3I8 which is attached to apin 3I9 in the rack 3I3 at one end, and to a pin 320 in the side plateI60 at the other pulls the rack. in the direction of the arrow 32I and alug 322 on the rack bears against the inner side of the side plate I60to define the normal position of the locking rack. In this position, theten teeth 323 of the rack engage between the teeth of the driving wheels66, 232 etc. in

.the accumulator 2 and prevent unintentional rotation.

The right-hand arm 32! of the manipulating lever 3 is made exactly likethe left-hand one 293, but its cam slot is without the recess 3| I.

For this operation, the manipulating lever 3 I is rocked rearwardly intothe position shown in Figs. 3 and 15. The arms 293 and 324 turncounterclockwise (as viewed in Figs. 2 and 3) about their headed screws290. The pins 296 (Figs. 14-17), 325 (Figs. 2 and 3) leave thedepressions 298, 321 in the side plates I60 and I59. At first, thecurved parts 309, 328 of the cam slots 301, 329 move idly past the guidepins 308, 330 but then their inclined edges 33I, 332 engage the pins andthe accumulator 2 is swung about the shaft I58 clockwise until the lugsI61 and I65 engage the abutments I68 and I66. In this position, the pins296, 325 engage in the depressions 299, 334 in the side plates I59 andI60, and the teeth of the driving wheels 66, 232 etc. in the accumulator2 engage with the transmission gears 45, 213 etc. in the columntotalizer I. The

ends I18 and- I19 of the reversing pinion shaft I11 are held at theupper end of their arcuate slots I and II by the semicircular seats 304.

When the manipulating lever 3 is thus moved anti-clockwise into theposition shown in Figs.

tion shown in Figs. I and 15, the hook III maintains the locking rackIII at its right-hand limit of travel, to tree the accumulator drivingwheels for rotation.

When it is desired to uncouple the accumulator I from the columntotalizer I, the manipulating lever I is returned from its Fig. Iposition into the intermediate position shown in Figs. 2 and 14. First,the pins III, III leave the depressions III, III in the side plates IIIand III and the inclined edges III, (Fig. 17) III (Fig. 4) of the camslots III, III in both arms engage the guide pins III, III and returnthe accumulator I into its normal position by swinging it anti-clockwiseabout the shaft III and the pins III, III are now again in the curvedparts III, III of the cam slots "1, III. At the same time, the hook IIIoi the arm III releases the rack III and the spring III again iorces thelug III of the rack against the inner side oi the side plate III. Theteeth III oi the rack again lock the accumulator driving wheels II, IIIetc. through their teeth. The pins III, III engage in the depressionsIII, III and the teeth of the driving wheels II, III etc. in theaccumulator clear the transmission gears II, III etc. of the columntotalizer I.

(14) The operation of the coupling and locking means for total takingfrom the column totalizer and subtractive transfer to the accumulaterFor this operation, the manipulating handle I is moved forwardly intothe position in Fig. 16. The pins III, III leave the depressions III,III and the curved edges III, III of both arms III and III clear theends I" and III of the reversing pinion shaft Ill, until the upper edgesIII III, of the slots III, III act on the reversing pinion shaft I'IIwhose ends I" and "I now descend in the direction oi the arrow III inFig. 16. As the shaft I'II descends the reversing pinions III, III etc.of the individual orders which are free to rotate on the shaft, roll onthe teeth of the driving wheels II, III etc. and, when the manipulatinglever I has completed its stroke, mesh with the transmission gears II,In etc. in the column totalizer I.

As the manipulating handle I moves into the position in Fig. 16, thecurved portion III, III of the'cam slots III, III slide idly past theguide pins III, III in both side plates III and III without shifting theaccumulator frame. The hook III of the arm III pushes the rack IIIagainst the arrow III (Fig. 18) and its teeth III clear the teeth of theaccumulator drivin wheels II, III etc. The pins III, III engage in thedepressions III, III of the side plates III and III.

when the manipulating lever I is returned into the idle position in Fig.14, the edges III, III of the slots III, III raise the shaft I'IIagainst the arrow III (Fig. 16) so that its Dinions III, III etc. aremoved clear 0! the transmission gears II, III etc. roll on the teeth ofthe drivins wheel II, III etc. and return into their idle positions. Thecurved edges III, III oi the arms III and III again engage the ends I"and ill of the shaft I11 and hold it in its idle position. The hook IIIof the left-hand arm III releases the rack III which, returning in thedirection 01 arrow III, locks the driving wheels II, III etc. The pinsIII, III engage in the depressions III, III in the side plates III andIII.

I! it is desired to transfer additively to the accumulator I a valueadditively introduced into the column totalizer I, the manipulatinglever I is moved into the position according to Figs. 4 and 16, and theoperations which have been described above for negative transfer arerepeated On the other hand, ii it is desired to transfer subtractivelyto the accumulator I a value which has been introduced additively intothe column totalizer I, the manipulating handle I is moved into thepositionshown in Figs. 3 and 15, and the operations described in sectionI I are performed.

(15) The suspension and securing means for the double totalizer The sideplates II and II oi the column totalizer I are equipped with integralstationary hooks III and III, respectively, as best seen in Fig. 19, attheir lower rear ends which engage the lower edge 'III of thedove-tailed rail II. For suspending the column totalizer i from therail, the following arrangement is provided.

A suspension bar III which is shown partly broken away in Fig. 19, andhaving a hook shaped ridge III at its free end for engaging the upperedge III of the rail II, as shown on larger scale in Fig. 2, is mountedto swing between the side plates II and II of the column totalizer I bymeans of trunnions III and III in holes III and III in the respectiveside plates II and II.

For securing the column totallzer i against lateral displacement on therail II, a catch III is mounted on the trunnion III and rigidlyconnected to the suspension bar III. The rear end of the catch isforked, forming a hook III which bears on the upper edge III of the railI I and a tooth III for engaging between the teeth of the rack III tosecure the column totalizer I against lateral displacement. A stud IIIextends between the suspension bar III and the catch III to which isattached a spring III whose lower end is secured to a pin III in theright hand side plate II. This spring tends to turn the bar IIIclockwise, forcing the ridge III of the suspension bar and the hook IIIof the catch III against the upper edge III 0! the rail II'.

A cam III, Fig. 20, at the lever edge of the catch III is provided forcooperation with a pin II! of a locking arm III which pin extendsthrough an arcuate slot III in the right-hand side plate II. The lockingarm III is fulcrumed about a headed screw III in the side plate II andits movement is limited by the ends Ill and III of the slot III.

A lug III which extends upwardly from the front end 0! the catch III isarranged for cooperation with a nose III of a bellcrank III which ismounted to turn about the hinge shaft III. A torsion spring I1! is woundabout the shaft III and its longer arm I" engages in a recess III in thetransverse stay III of the accumulator I, as best seen in Fig. 2. Thisspring tends to turn the bellcrank III anti-clockwise about the shaftIII and forces the nose I" against the lug III of the catch III. Thestrength of the spring is Just suflicient for holdaccuser (16) Theoperation of the suspension and securing 'means When it is desired toremove the double to-' talizer from the rail H, the locking lever 363 isturned clockwise from the locking position in Fig. 21 into the unlockingposition in Fig. 20 in which the pin 361 is against the end 312 of theslot 353. The pin now clears the lower edge 365 of the catch 353. Bymeans of the handle 334, the bellcrank 314 is now turned anti-clockwiseand its nose 315, through the lug 313 on whose upper edge it acts, turnsthe catch 353 and the suspension bar 352 anti-clockwise about thetrunnions 353 and 354. The ridge 351 of the bar 352 and the hook 360 nowclear the upper edge of the'suspension rail if, and the tooth 36] of thecatch 359 clears the rack 341, so that the double totalizer can now beremoved.

When the handle 333, 383 is released, the suspension bar 352, the catch359, and the bellcrank 314 are returned into their normal positions bythe spring 361, and the tooth 332 of the bellcrank 31! turns the flap203 anti-clockwise (Fig. 2) about its trunnions 204 and its edge 205 isplaced against the edges 201, 221, 258, etc., of the levers I39, 11 etc.in the totalizer 2, so that unintentional turning of the wheels in thecolumn totalizer i and the accumulator 2 is prevented.

(17) Placing the double totalizer on the suspension rail When it isdesired to place the double totalizer on the suspension rail H, thehandle 333, 384 is pressed, the column totalizer l is placed on therail, and the handle isreleased. Spring 360 now turns the suspension bar352 and the catch 359 clockwise, the ridge 351 and the hook 360 againengage the upper edge or the rail ii, and the tooth 36! engages betweenthe teeth of the rack 341. The bell'crank 316 'returns into the position shown in Fig. 20. The locking arm 363 is now turned anti-clockwiseinto its locking position, Fig. 21, in which its pin 361 bears againstthe end 3" of the slot 369. The pin 361 raises the catch 353 by its cam366 and the upper edge 353 of the rail His firmly engaged by the ridge351 and the hook 360.
